lymph nodes

Small oval or bean-shaped bodies, up to 2 cm in length, situated in groups along the course of the LYMPH drainage vessels. The nodes have fibrous capsules and are packed with lymphocytes. The main groups of lymph nodes are in the groins, the armpits, the neck, around the main blood vessels in the abdomen, in the MESENTERY and in the central partition of the chest (the MEDIASTINUM). Lymph nodes offer defence against the spread of infection by producing ANTIBODIES, and become involved in the spread of cancer. They can become cancerous, forming LYMPHOMAS.

Lymph nodes

Small, bean-shaped masses of tissue scattered along the lymphatic system that act as filters and immune monitors, removing fluids, bacteria, or cancer cells that travel through the lymph system. Breast cancer cells in the lymph nodes under the arm or in the chest are a sign that the cancer has spread, and that it might recur.
